This invention relates to an -Xray or radiographic apparatus and particularly Yto such an apparatus Comprising a support for a patient While X-ray pictures are being taken of such patient. Asis Well known, it is noiv Va very common practice to take X-fray pictures for the purpose of diagnosing' ailments. It is also a common practice to takea series of Xi-ray pictures of certain organs inl the.

body,I particularly the stomach. At vsuch times, certain chemicals `are administered internally totheV patient' which .assist in obtaining thevX-ray images. While such picf tures are being taken it is desirable that the body of the patient be in normalreondition or position so that the organs observed, such as the' stomach, will function in their normal manner. A f

It is'also desirable that an apparatus be provided in Which the ycassette or plate hold-1. ing member may be'quickly set in a plurality of-di'erent positions so that a series of4 pictures may be easily and quickly obtained.

It is also desirable to have a portableapparatus of the character referred tol Whiclican be readily'inounted lin different positions and supported in different places,

Itis an object ofthis invention, therefore,-

to provide an X-ray apparatus comprising a casing'iadapted to hold the cassette,-vvli1ch casing has a top portion for supporting the body of the patient having a recess therein adapted to receive' the Convexportionof the body so that tlietbody-vv-ill notbe .com-

The casing 14C is attached to table vll-7 by having a pair of handles le hung on small levers 52 pivoted at the side of table .47' and having their ends engaging stop pins y53 In operation, the device of this invention A.comprising casing le yand attachedparts,

lwill be disposed on the desired support which, as shown, may be a horizontal table or a vertically inclined table. The .device is portable and easily moved from oneplace to another. It is, therefore, an easy matter to transport the same from onepart of the hospital 'or' other institution, to the Vother part thereof. The" position of the patient when supported on the device is illustrated in Figs. 2 and o. If the patient lies flat Von his stomachon a flat support the body is pressed upwardly andthe stomach and otlier'organs are pressed against thespine. This places the stomach, or other organs in an abnormal position and tliisabnormal j position will affect the normal functioningk of the organs.' In order to relieve this'iipwardpressure and to have the body and the internal organs, such as the stomach, inV perfectly normal position., the recess is provided inthe top portion or cushion l15c about the opening 15b.

pressed upwardly to .cause the internal organs to. assume abnormal; positions'. If a radiographic examination is to, be inadegofv i the fluoroscopic screen beneath the opening ll. Theimage -made by the X-rays will be vformed on said screen `andfthis image may be observed by the operator from .the front of the device by looking in the -inirror43. i 'fr an jV As previouslyl stated, it is common practice to make a series of X-,ray pictures showing the functioning of an internal or-v gan,'such as the stomach. The "present ap-V paratus is conveniently arranged to expose the plate in such a series of picturesglf twelve exposures arev to be made on the plate the ,lever 22 will be moyedto .its dotted position so that plate 2O is disposed across opening A15" and only the portion 20a is capable of transmitting the X-rays. The

l The front or con-l vex portion of the body can thus enter V this p, recess, as shown'in Fig. 3 and will not be is made on each zone. lever 38 the zone 55d may beexposed so Vthat they series of four exposures will be ob-,`

'to the middle notch 3.0%.,KA This brings thel yzone 541 under the exposure opening and another exposure is made. AThe lever 38 is 'thenmovedto the '-otherend notch 30a'and the zone 55c is brought under the exposure opening and an exposure made on ,tliispart ofthe plate.` The lever 3l is now moved zone 54d of Vtheplate `5ft-*is brought `under the exposure opening. The lever 38 is now again successively movedinto-L vits vnotches 30a again to move the Yplate ltransvereey across the exposure opening'. vWhen the The lever 33 is also f 'vll-he vinto the ,next adjacent notch la andthe plate has had lthe three yexposures transversely thereof the" lever 3 1y will'again lbe moved. and these operationsl will continue untilthe twelve exposures have been Vmade on the plate. The. successive zexposures can thusbe very quickly and accurately made.

Ifit is desired to make four-exposures,

the barvltC will be rotated onyits trunnions degrees by turning knob '14h to the right of under the exposure opening andan exver- 22 will be moved to` full line position until it engages vthe lower stop 4t2/Q The j lever 3l willbe placedl in one of the notches lea and the lever` 38 will `be engaged in one ofits endiiotches. The plate will -fnow have its zone 55av at lonecorner thereposure 'will-now be made in this portion of y i ,the plate.'v Atthis time the plate 20.` and lelofi' shown inl 7. The lever 3S will no w be swung to its other 'end position and ther-zone .heb of the plate will be broughtunder theexposure opening.

g, it being understood that the exposure tainedon the plate. lf the.. device. isfsupported, vas Ashowninv Fig. 2, the operation .of the exposures willbe just the sja-megas .above'.described.4 v,It willthiis be seen that 'f -thejplate 20mn be disposed in a plurality of positions and forms, in effectJ a shutter controlling the opening which is permeable to the X-rays. rlhis plate is, as described,l positioned in accordance with the number ofl pictures it is desiredrto` take upon one film `or plate, and, as above described, the Ydevice can be used to make the standard size pic- Nture on a standard size plateor film or a seriesof smaller pictures may be takencn the plate or film. Alem as above set forth,

The lever 3l .will then y moved gto'it'sotherfnotch lland 'zone f5.5@

will V,be broiigl'it under` the 'exposure .open- .1110' By again. .moving isol . a support, a. top portion on said casing tormm LA the device is portable and may be disposed in various positions aii-d on various supports.

From the above description it is seen that applicant has provided an extremely simple and eiiicient X-ray apparatus and one having a high degree of utility in making radiographic examinations and radiographic pictures. The device is simple and compact and, as stated, can readily be transported and conveniently supported in various positions. 'ilhe device is arranged to support the patient vvith the body and theorgans'thereot in normal position so that the various positions of Vthese organs in their operation may be accurately photographed. The device has been amply demonstrated in actual practice aiid found to be very successful and efficient. f

It Will, of course, be understood, that various changes may be made in the form, details, arrangement and proportions of the parts Without departing trom the scope ot applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims.
